What tools are needed to add refrigerant to a car?
1 Answers
To recharge a car's air conditioning system with refrigerant, a refrigerant recovery and recharge machine is required. Below is the specific process for adding refrigerant: 1. Preparation: Before adding refrigerant, you need to prepare tools and materials such as a car refrigerant recovery and recharge machine, refrigerant (most car air conditioning systems currently use R-134a refrigerant, and different refrigerants must never be mixed). 2. Connecting the hoses: Connect the hoses of the car refrigerant recovery and recharge machine to the high and low pressure pipes of the car's air conditioning system (red connects to the high pressure pipe, blue connects to the low pressure pipe). 3. Vacuuming: Once the hoses are properly connected and the refrigerant recovery and recharge machine has completed its self-test upon startup, you can begin the vacuuming process for the car's air conditioning system. 4. Adding refrigerant: Only after the vacuuming process is complete can you start adding refrigerant. Based on the maximum refrigerant capacity labeled on the vehicle's air conditioning system, set the recharge capacity, time, and type on the refrigerant recovery and recharge machine. After confirmation, the machine will automatically begin adding the refrigerant.
